Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.

This report describes findings from a telephone survey with 1,316 people conducted in February 2021. The survey examined how people respond to public health and social measures (PHSMs) to prevent COVID-19. The sample is representative of households with access to a landline or cell phone, but does n...ot include people without access to phones. As phone penetration varies by country, findings should be interpreted with caution.

This publication articulates the WHO Botswana Country Office’s focus and investment needs for the biennium 2022–2023, building on achievements, networks, and partnerships fostered in 2020-2021.
As the leading health authority within the United Nations system in Botswana, the WHO Country Offi...ce has been at the forefront of supporting the government to improve health since 1996. The WHO Country Office supports the Ministry of Health in realizing the health goals the Government of Botswana defines. Acknowledging that as an upper middle-income country, Botswana provides the bulk of its resources for implementing health programmes, the WHO directly brings technical expertise to the table by collaborating with relevant partners. Where the country office has limitations in terms of human resources with the requisite expertise to answer the country’s needs, the regional level and headquarters of the WHO will be mobilized to provide the necessary support.

What are the common health problems of refugees and migrants arriving in the European Region?
The most frequent health problems of newly arrived refugees and migrants include accidental injuries, hypothermia, burns, gastrointestinal illnesses, cardiovascular events, pregnancy- and delivery-related complications, diabetes and hypertension. Female refugees and migrants frequently face specific... challenges, particularly in maternal, newborn and child health, sexual and reproductive health, and violence. The exposure of refugees and migrants to the risks associated with population movements – psychosocial disorders, reproductive health problems, higher newborn mortality, drug abuse, nutrition disorders, alcoholism and exposure to violence – increase their vulnerability to noncommunicable diseases (NCDs)
